JOSEPH F. FOSCl-IINBAUR, OE RIDGELAND, ILLINOIS, ASSIGNOR TO THE UNIONSPECIAL SEYVING MACHINE COMPANY, OF CHICAGO, ILLINOIS.

FOLDING GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 566,676, dated August25, 1896.

Application filed e 8, 1895. Serial No. 551,441. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH F. FOSCHIN- BA'UR, a citizen of the UnitedStates, residing at Bidgeland, in the county of Cook, State of Illinois,have invented certain new and useful Improvements in Folders, of whichthe following is a description, reference being had to the accompanyingdrawings, and to the letters and figures of reference marked thereon.

My invention relates to an improvement in sewing-machines, andparticularly to a folder attachment for the same.

lhe object of the invention is to provide a double-folding device forseaming together.

two pieces of fabric, and I preferably apply the folder to asewing-machine having a cylind rical bed-plate or horn, in which machinethe feed is longitudinal of the arm.

The particular work for which I have designed the folder is inconnection with the manufacture of shirts, trousers, and overalls. It isspecially constructed to allow for the passage through it of anincreased thickness of fabric, such as takes place when a crossseam isto be passed through the machine; but it is very desirable, and willhave its greatest utility, in the manufacture of shirts of a certainkind in which a gusset is inserted be tween the flaps.

It has heretofore been proposed. to provide folders for use when twopieces of fabric are to be scanned together, and, indeed, to provide aspring-folder with yielding portions to allow of the passagetherethrough of increased thicknesses of material; but the presentinvention has been found especially adapted to the work above mentioned,and obviates many dificulties which have heretofore arisen in the use offolders.

The invention therefore consists in the matters hereinafter described,and referred to in the appended claims.

In the accompanying drawings, which illustrate my invention, Figure 1 isa perspective view of so much of a sewing-machine as is necessary for acorrect understanding of my invention, showing my improved folderattached thereto. Fig. 2 is an end view of the cylindrical bed-plate,showing the folder attached. Fig. 3 is a plan view of the blank fromwhich the folder is struck up, and Fig. 4 is a rear View of the folder.Fig. 5 shows a plan view of the seam made by the folder.

In the drawings, A represents the bed-plate of a sewing-machine, thisbed-plate being herein shown as cylindrical in shape, the end beingclosed by the removable cap B.

C represents the throat-plate secured to the bed-plate by the screws (1,and at its forward end it extends quite a distance beyond the end of thebed-plate, being provided with screw-threaded openings for theattachment of the folder. This throat-plate has the necessary and usualslots for the passage of the needles and the teeth of the feed-dog.

D represents a presser-foot, having openings for the passage of theneedles (1, which are secured to the needle-bar in the ordinary way, andare herein shown as arranged at an angle to one another respecting theline of feed, though this, of course, is not essential.

F is a resser-bar to which the presser-foot D is secured.

The folder is represented at Gr and is attached to the throat-plate bymeans of screws e passing into the holes of said throat-plate, the endof the throat-plate being flattened to allow of the better securing ofthe folder G. This folder is preferably made of a single piece of sheetor spring metal, and when bent to proper form consists of the fiatportion 1, secured to the throat-plate, the intermediate horizontalportion 2, and the upper portion 3.

The lower or flat portion 1 has a rearwardlyproj eetin g spring-tongue aformed on a twist,

' as shown, its inner edge being curved to form one side of the scrollproper and having a downwardlyprojecting lip 5, which acts as a guidefor one side of the fabric, that is, of the lower piece of fabric. Theupper portion 3 has also a rearwardly-projecting springtongue 6, whichis curved in the opposite direction to the tongue 4:, and its inner edgeforms the opposite side of the scroll and acts as a guide for the inneredge of the upper piece of fabric.

Projecting reaiwmrdly from the middle portion 2 isa spring-tongue 7curved or twisted, as shown, its sides or faces being made to conform inshape with the adjacent inner faces of the tongues a and (i,wherebybetween each face of the middle tongue 7 and the adjacent tonguesis formed a passage for the fold in one piece of fabric, the tongue 7serving to separate the layers.

It will be seen that by the arrangement of the spring-tongues anyincrease in thickness of the fabric passing through the folder isreadily accommodated, so that there will be no binding of the goodsagainst the folder to prevent the proper feed of the goods, the tonguesbeing sufficiently flexible at the rear end to allow of any reasonablethickness of fabric being passed through.

In the drawings I have shown a portion of a shirt being sewed on themachine with a gusset being inserted, the spring-tongues allowing thepassing of the thickened portion of fabric when one piece of the goodsis turned to one side and the gusset begins to be folded to unite withthe other part.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A folder comprising a base, a central portion and an upper portion,the upper and lower portions being secured to the central portion onopposite edges thereof, each of said portions having arearwardly-extending part constructed to form between them two channelsfor folding and guiding the fabric, said parts being independent andunconnected and each of the outer ones forming one entire wall for oneof the channels and the central portion forming respectively the sidewall of both channels; substantially as described.

2. A folder comprising a suitable body portion formed with openings forthe insertion of pieces of fabric, and having a plurality of rearwardlyextending tongues, twisted or curved to guide and fold the fabric and anintermediate tongue having each of its faces conforming to the adjacentface of the proximate tongue; substantially as described.

3. A folder comprising a suitable body portion, formed with openings forthe insertion of pieces of fabric, and having a plurality of rearwardlyextending tongues twisted or curved to guide and fold the fabric, and anintermediate tongue having each of its faces conforming to the adjacentface of the proximate tongue, one of said tongues having adownwardly-projecting lip as 5 which acts as a guide for one edge of thefabric; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH F. FOSCIIINBAUR.
